Toni Wilen adding PPC emulation in WinUAE?

[eliyahu]

The price of AOS 4 is very similar to windows. Any way I would get me a copy of AOS4 for classic ppc if winUAE could run it.
So count me in for an extra copy of AOS4!

same here. for me the price alone is worth the ability to run digital universe and codebench on my laptop. i don't have a lot of confidence that one day AOS4 will run in UAE -- but if it does, awesome!

Again, for what possible reason?!  Surely a new user to the platform and the money from OS4.1 classic is a "good thing"?

absolutely! i'd pay double for a license that would let me run on winUAE. i'd finally have that amiga laptop i've been waiting on for so long.

looks like toni is moving to QEMU faster than expected. here's his latest update over on EAB:

QEMU PPC is still work in progress (by Frode and me), QEMU-side is not  yet included. It run for the first time few days ago. It is not stable  enough yet but hopefully soon...

for those of us who've been playing with PPC support on our PCs, this is great news. OS4.1 runs fine once you disable petunia, but painfully slow. QEMU should help address this somewhat. i can't wait to have my laptop running SUSE, AOS4, and AROS with reasonable performance. sweeeeet.

yet more progress on QEMU integration from toni over on EAB:

Inter-thread messaging bottle-neck is now mostly gone.
cybppc.device (CSPPC built-in SCSI) works under OS4
Media Toolbox works.
Installing works.
Installing still takes forever (about 1 hour). See below. (But as I mentioned previously, boot image fade is now really fast)

Need to be fixed before public version:

All timers seem to run really fast (20x+), key repeat is instant, floppy  clicks really fast. Probably (and hopefully) explains remaining  performance problems. (It is possible huge number of timer interrupts  takes most of remaining CPU time..)

QEMU seems to have multiple timer emulation modes but they are all quite difficult to understand..

"Unfortunately" PPC CPU has built-in counter + interrupt when it  underflows, count rate is bus clock / 4, apparently this counter is used  for OS4 timer.device. Possibly detection of bus clock is also wrong.
